Fig. 1 is'saJ middle, longitudinal section of a multiple-passage Ahose embodying Vrny invention intits preerredrform, cable-lengths constituting parts of the structure being shown in elevation.

Fig. 2 is a section on line 2;-2 of Fig. 1i.

Fig. 3 Vis a breakfaway middle sectionA of a' multiple@passageendV fitting for the hose and Y swivel connections for supplying fluid to or receiving fluid from the several passages of the hose.

Fig. 4 is an elevation of a pullout and reeling assembly in association with the hose. Y

Referring to the drawings, and at first to Figs. 1 and 2, the particular hose chosen to be shown here for purposes of illustration and not of limitation has three fluid passages which in each length of hose is defined by a central supporting cable l0, an inner hose tube ll Vspaced from and surrounding the cablaan intermediate hose tube i2 spaced from and surrounding the inner hose tube il, and an outer hoseV tube i3 spaced from and surrounding the intermediate hose tube l2.

These hose tubes preferably are of graduated wall thicknesses as shown, the outer tube being of the greatest wall thickness, for strength, because it is subjectedv to high strain not 'only because of its .relatively large diameter but also becausethe pressure of duid next within it may 3,1940, serial No. 355,1.12 s Cisnes'. (crass-L22) v be to only a relatively srnall` extentoset by atmospheric pressure or, near the top of the well, only a small head of water` ordrilling fluid, whereas thepressures on opposite faces of the `wa'iis of 'the other tubes are more nearly equal- Y ized and also those tubes are subjected to lighter strain, other things being equal, by reason o their relatively small diameters.V

Swedged upon eachend of eachlength l'of' the outer hose tube isa-coupling ring or doublee Walled sieeve i3@ provided with a gasketlSb and `onned with an vinternal annular shoulder-I3c and with external threads for engagement'by an annular coupling I6.

Similarly' eachV end oieaclilength of the interi mediatel hose tube` l2Y has swedged thereon* a couplingr ring or double-walled sleeve `lZtpro vided` with Va :gasket` 2b and formed with an internal annular shoulder IC and also with radiating spider arrnsf lid adapted to seat at their outer ends upon the annular shoulder I3@ of the outer tubes coupling ring i3?. .i i

Likewise eacfnend o each length of the inner hose 4tube! l has'swedged' thereon a coupling ring or double-walled sleeve Iia provided with a gasket Hb and formed with aninternal annular shoulder licand with radiating spider arms Hl `adapted'to seatagainst the annular shoulder I2c `of the intermediate tubes coupling, ring |221.` Each endof each length of cable Vii] has see cured. thereon-a taper-jaw end-tting i l5 the toothed jaws of which are sprung Vagainstthe lcable by`a taper-threadednutffi and each; of the end-fittings i5 is formed with radiating spider arms ld adapted to seat against the annular shoulder Hc of the coupling ring l lSAV of the inner hose tube Il. i

In the assembling of these parts the coupling rings 13a are mounted on the two ends of the hose length I3 and a coupling ring 23 is'mounted on one end of the hose length i2 and the other endV of the hose length l2 is passed into and through the hose length I3 untilV the spider armsV ld engage the shoulder 53 at the first mentioned end. The hose length l2 is then stretched or the hose length I3 is compressed lengthwise, or both, to cause the unequipped end of the length l2 to protrude from the lengthlS and while it so protrudes the second couplingV ring 12a is mounted upon it. Upon release o theV two hose lengths the spider arnrs lZd of the The inner hose length i I and the cable'length Hl are incorporated in the assembly in the same way, in succession, exceptthat the cable 5&3 is not adapted to stretch very substantially, which makes it necessary to obtain piotrusicn ci its la'stequipped end chiefly by lengthwise cor pression oi the assembled hose lengths.

A series of the composite lengths of hose are `then coupled by means of threaded couplings such as the coupling t4 and the resulting line of Y hose is manipulatedV as desired.

Figs. 3 and 4 show convenient end fittings and apparatus for use of the hose forwell-drilling or well-pumping purposes. for example.

In Fig. 4 is shown a series of driven pull-out and hold-back rolls l1, i8, I9 and guide rolls 25 to 24 cooperating with a hose reel 25, here shown comprises a unitary casting 29 formed with passages 39, 3l and32 communicating with the re'- spective passages of the hose, the casting being Vcoupledtothe upper end of the adjacent hose section, inclusive of the' cable section I0, in the same manner as the upper hose section in Fig. 1 is coupled to the lower hose section in that figure.

The outermost passage 32 of the Acasting-extends upward only part way of the casting, in a large-diameter part of thelatter which terminates at a shoulder 33, and the outer wall of this 'passage-is formed with apertures 34, 34 through which the passageY is in communication with an annular internal groove 35 formed in a distributor ring 36 which surrounds the casting and is incommunication with a stationary conduit 31. a

`The distributorV ring 36 is provided with a supporting bearing 38,V packing rinesSS, 35 and packing nuts 40, 40.

Similarly the intermediate. passage 3l extends only part way to the top of the casting, in a por- 'tion 'thereof of intermediate diameter, and

through ports 4l, 4| and an internal annular groove V42 in a distributor ring 43 it is in communication with a stationary conduit 44.` The distributor ring 43 is provided with a supporting bearing 45, packing rings 46, 46 and packing nuts 41,'41.

The innermost passage 30 extends` to the top of the casting, where it is closed by a screw-cap 48, and through ports 49, 49 and an internal annular groove 50km a distributor ring 5I it is in communication with a stationary conduit 52. The distributor ring 5I is provided with a supporting bearing 53, packing rings 54, 54 and packing nuts 55, 55.

The construction as described provides the several advantages set out in the above statement of objects and various modifications `are possible within the scope of the appended claims.
